Application filed October 25, 1915. Serial No. 57,664.

To all whom 2'? may concern:

Be it known that we, GEORGE F. Gnonn and JULIUS V. .Mnynnlno, citizensof the United States, the 'i'ormer a residentot Evanston, Cook county,Illinois, and the latter of Chicago, Cook county, Illinois, haveinvented certain new and useful Improvements in Trunk Lockinglliechanism, of

which the following is declared to be a full,

' by a movable locking member, located. on the outside of the trunk orother object, thereby dispensing with catches or locks at various placeson the outside of the trunk, which catches must be operated individuallyin fastening the two hal vcs of the trunk together.

Other objects are to simplify locking mechanism of this class, and tostrengthen and otherwise increase the eliicieucy thereof, and with allof said objects and advantages in view this invention consists in theseveral novel features of construction, arrangemonk and combination ofparts hereinafter described and claimed.

The invention is clearly illustrated in the accompanying drawing, inwhich: 7

lfigure 1,,is a vertical section through a trunk, showing in sideelevation, a trunk locking mechanism embodying a simple form of thepresent inventioh, in locked position, applied thereto; Fig. 2, is aside View of the same parts, with portions of the trunk body brokenaway, the locking mechanism being shown in unlocked position and the twotrunk sections partly opened; Fig. 3, is a side elevation of'a fragmentof the trunk, showing the outer locking members; Fig. 4, is a detail,horizontal section taken on line ll, Fig. 1; Fig. 5, is a detail,horizontal section taken on line 5-5, Fig. 1; Fig. 6, is a perspectiveView of a lock bar shifting member and Fig. '7, is a side elevation ofa. slightly modified form of lock bar shifting means.

Referring first to Figs. 1, to 6, inclusive of said drawing, whichillustrate the preferred embodiment of theinvention, 10,11, indicate thetwo sections or members of a trunk, hinged together as usual, andcapable of containing many of the common and well-known compartmentdevices and other apparatus; for receiving clothes and other baggage.Near one end or the meeting edges 12, 13, of the two sections is theouter locking mechanism 14:, which may comprise the usual hasp member15, mounted on one section and socket member 16,-

mounted on the other section and adapted for locking engagement withsaid hasp member in accordance with the common and well-known practice.In the form shown,

the hasp member 15, has a hinge joint at 17,

whereby the hinged part. mayswing toward and away from the socket memberin looking or unlocking the'trunli, and said hasp member 15, ispivotally, mounted on: the trunk section 11, on a horizontal .piyot,whereby it may be swung-upward from the position shown in full lines inFig. 3, to that shown in. dotted lines and Vice Verse, for the purposeof actuating the internal locking mechanism. Conveniently the haspmemberjhas an inwardly extending pin or bolt 18, rigidly secured theretoand projecting through an opening in the trunk section and turningfreely therein. The innor end of said pin or bolt 18, is squared, f

and rigidly secured to said squared cnd'is a segmental rack 19, theteeth of which mesh with teeth 20, on a lock bar 21, which is slidablymounted on the inside of the trunk section 11. In the form illustrated,said teeth 20, are formed in said lock bar 21, near one end thereoflandthe segmental rack has two fiat sides 22, 23, arranged at rightangles toeach other and adapted to strike against the adjacent toothed edge ofthe lock bar, to thereby limit the movement of said bar, and hasp memberin either direction, the parts being so proportioned that movement ofthe hasp member through an arc of degrees shifts the lock bar 21 throughthe necessary distance to lock or unlock. the internal lockingmechanism. The lock bar is guided to move in a lengthwise direction bystraps 9.5, secured to the trunk section 11 and overhanging the bar. Onthe adjacent side opposite trunk section 10, are fastened a plurality ofstationary or fixedly secured internal lock members 25,

which project across the meeting edges of the two trunksections and arearranged for locking engagement with the sliding lock bar 21. In theform shown said internal lock members 26, are formed with notches 27, intheir upper edges, near their outer ends, adapted to receive lock boltsor lugs 28, carried by, and preferably formed integral with the slidinglock bar 21. Con veniently the notches 27, have inclined edges 29inclined upwardly and outwardly, and the lock bolts or lugs, 28, havesimilarly inclined edges 30, adapted for engagement with and coactingwith said inclined edges of the notches 2'7, to force the two trunksections together. At the upper ends of the inclined edge portions areupstanding lugs 31, which are adapted to engage With straight edges onthe rear sides of the lock bolts or lugs 28, whereby when the parts arein locked position said straight edges engage each other and positivelyprevent relative movement between the two trunk sections. When the lockbolts or lugs 28, are formed integral with the lock bar 21, notches 32,may be formed in said lock bar behind and below the lock 'bolts or lugs28, for tllu reception of the notched ends of the inte: 121i lockmembers 26, and said notches 32, are made long enough to permit the lockbelts or lugs 28, to be Wholly withdrawn from the notches in theinternal lock members 26, as clearly illustrated in Fig. 2, where itwill. be seen that said notches 32, are position registering with theends of the internal lock members 26. In operation, the external lockingmechanism is unlocked and the beep member swung into the position,indicated in dotted lines in Figs, 2, and, 3, to unlock the internallocking bar is thereby raised out of locking engage ment with theinternal lock members, through the .instrumentality of the segmentalrack. The two trunk sections may then be swung open. To lock the trunkthe sections are swung together, and the heap member is thereafter swungdown into register with the external socket member, the straight edge22, of the segmental rack thereupon striking against the adjacent edgeof the lock bar 21. The hasp member is then locked to the socket memberas usual, thereby locking the two sections together at a plurality ofplaces on its interior. The trunk cannot be unlocked said places withoutfirst unlocking the exterior locking mechanism. 1

In the modified form shown in Fig. 7, the hasp member 15- is connectedto the lock bar 21 by an eccentricaily disposed pin 19*, secured in onemember and projecting through a slot in the side of the trunk sectionand em gaging the other member, In this case the pin or bolt 18?, simplyacts as the hilcrmn or 29, of the notches 27,

mechanism; the lock,

pivotal connection between the hasp member and trunk section; the lockbar and internal lock members may be constructed substantially as in thepreferred form.

More or less variation of the exact details of construction shown anddescribed is possible without departing from the spirit of thisinvention. We desire therefore, not to; limit ourselves to the exactforms shown and described but intend in the following claims to pointout all of the invention disclosed herein.
